(GRANTED UNDER THE ACT OF MARCH 3, 1883; 22 STAT. I. Q25.)

The invention described herein may be used by the Government, or any of ltSOificers or employees in prosecution of work for the Government, or by any other person 1n 5 the United States, without payment to me of any royalty thereon. in accordance with the act of March 3, 1883.

This invention relates to a primer for cartridges, and has particular reference to the metallic composition thereof.

Primers for the ignition of cartridges and for other purposes must be made of a metal which possesses the characteristic of elasticity so. as to readily yield to the blowof the firing pin and of strength to withstand the excessive premure produced. The material must alsopossess a high degree'of resistance to the chemical action of the ingredients of the ignitingcharge of the primer.

I have discovered that the foregoing requirements are admirably fulfilled when the known as Monel metal and consists of nickel 75%, copper 23.5% and iron 1.5%.

Whi'e the composition cited has been found to have given excellent results it is byno means intended to limit my invention to the ingredients and proportions men tioned in the formula for Monel metal but to include suitable alloys containing a high percentage of nickel.

I claim: I

1. A primer made of an alloyzcontaining nickel 75%, copper 23.5%, and iron 1.5%. 2. A primer made of a corrosion resisting alloy containing a high percentage of nickel.

3. A primer made of an alloy containing a high percentage of nickel.
